IMPROVEMENT IN VEHICLE- WHEELS.

Specification forming part of Letters Patent No. 192,934, dated July 10,1877; application filed December 18, 1876.

To all whom it may concern Be it known that I, MARTIN JAcKsoN RACER, ofLa Grange, in the county of Fayette and State of Texas, have invented anew and Improved Vehicle -Wheel, of which the following is aspecification:

Figure 1 is a side elevation, with parts broken away to show theinternal construction more clearly. Fig. 2 is a transverse section. Fig.3 is a detail sectional view taken on line :10 m, Fig. 2.

Similar letters of reference indicate corresponding partsr The-object ofmy invention is to provide a vehicle-wheel that is capable of beingexpanded so as to fit the tire, to obviate the necessity of removing,contracting, and replacing the tire.

The invention will first be described in con nection with the drawing,and then pointed out in the claim.

Referring to the drawing. A is the felly, made up of the sections B (l,which are beveled at each end, leaving a wedge-shaped space betweenthem, the larger portion of capable of drawing the wedge toward thetire.

E is an iron hub, provided with mortises b 'for receiving the spokes,and with an annular space, 0, in which a beveled ring, (1, is placed.The hub consists of two parts, F and G. The part F contains the mortisesand thering or tipsf, which bear against the ring d. The

outer ends or tenons of the spokes are fitted to holes bored in thefelly, which do not pass entirely through. Three or more set-screws, 9,pass through the part G, for forcing the ring d against the inner endsof the spokes V and setting them out radially.

When the wheel is to be tightened the part G is slightly loosened, andthe ring 01 is forced in by means of the screws g, which, by itsengagement with the beveled ends of the spokes, forces them out radiallyand sets the felly firmly against the tire. The part G is thentightened, and the wedges D are removed from their places and dressedsufficiently at their smaller ends to permit of drawing themsufficiently into the spaces between the ends of the sections of fellyto tighten the felly.

The concavity of the sides of the wedges prevents lateral movement inthe ends of the felly-sections.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- I The wedge D, concaved on the sides, and fittingover convexities in the sections B G to prevent lateral displacement, asdescribed.
